  Cant decide 2x1tb drives or a 2tb..

For a long time now, every drive I buy is double the capacity of my previous one. At first glance at my usual merchant sites I was happy to see that 2tb drives had finally become cheaper for their relative capacity compared to the 1tb's.

However a strange annoying thing has happened. There ares**tloads of those greendrives with wtf 5400 rpm spindle speeds now..

The new drive/s will be used regularly.
Do I get 2x hd103sj, samsung spinpoint s3 (1tb) cos theyre very cheap, yet came close to top in performance or should I get the hitachi deskstar HDS722020ALA330 (2tb) which i think is more average. I think they were released at different times, so I don't know what to make of the reviews. Its the only 2tb in the same price range that is 7200 rpm.

Im reading this, I think read access time is the most important spec for averaging computer use, but hey Im no computer expert. So yeah, what should I do. thanks!

Don't get either.

Here is a wd green with 64mb cache, 2tb for $90/s&h.
http://www.newegg.com/Product/Product.aspx?Item=22-136-514&...llFullInfo

With bench testing it, it is only slightly slower then my 1tb seagate 7200.12 with 32mb cache ($80-$90)
The wd black is the same speed as the seagate.

That link you posted is outdated from 2009.
Most of the hdd listed are either low cache or low rpm.(most are not high in both)

The wd black and seagate .12 are said to be the best bang for the buck.

I have kept up on these seagate hdd's a bit. You never want to buy the 7200.11 1.5tb drive.
A large portion of these drives have had problems. That is why the .11 was out for about 3 months, then was quickly replaced by the .12 series.
Though if you update the firmware it is supposed to help.
Read some of the Newegg reviews.

EDIT:
Also the 7200.11 is not as fast as the .12 with the dual platter configuration.

Thanks for the warning. I did examine the reviews ahead of time. It's a risk, but I think it's manageable.

From what I could tell there's a moderate chance of getting a defective drive. I also think a fairly high percentage of the DOA's have been due to improper packaging of "OEM" drives for shipping...which has supposedly been fixed.

I'm willing to try it with newegg's return policy. I plan to stress-test the hell out of it upon receipt (as I do most all hardware) to accelerate early-life failures.

I've seen the same issues brought up over the past couple of years with Seagate, Samsung, Hitachi, and Western Digital drives, and feedback has ranged from DOA to no problems after 2 years. The warranty is 3 years, and I do have a robust backup protocol.

I'll report what I find re: packaging and stress-testing.

I just got the HDD and the RAM I ordered and here's my promised report on the packaging.

The HDD is VERY well packed for shipping. The BARE drive is enclosed in a sealed metalized ESD pouch, then completely surrounded by about 1" of bubble-pack, then enclosed in a tight-fitting box that keeps it from moving around, THEN surrounded by enough folded brown-paper to keep that box from moving around and enclosed in an outer box.

However, that could be because I ordered a second item which required a second outer box. I suppose it's possible the packing could have been less robust had I ordered just the HDD. People had reported that earlier "OEM" drives were packed in a way that let them bounce around in their boxes with little or no bubble-pack. Obviously being dropped or tossed could seriously damage a drive under those conditions.


edit to add:
HDD prelim testing proceeding fine. NOT DOA!
edit to add:
HDD test update
Using freeware "HDspeed"

0 errors ~44 hours of continuous mixed, Read, Write, and R/W/Verify ops

Also...

Found another nice little HDD performance assessment tool. I mostly like it for the random access read test it performs. It's not as flexible as HDspeed in that to get it to test different physical parts of a disk, you have to create multiple partitions and test them individually.
Freeware DiskTT
http://www.snapfiles.com/get/disktt.html
(I should also add that DiskTT may support only 32bit OS. At any rate, My test/burn-in machine is 32bit WinXP Pro)

(note: this was just a casual test. I had a handful of system processes running in the background that I would normally disable during tests. I did disable all anti-malware processes)
(note: DiskTT's sequential Read and Write tests begin at the start of the target partition. Unless you specify a large enough total data transfer to cover the entire partition, you obtain only a snapshot limited to the starting physical region of the drive/partition.
I think the "Random Access Reads' span the entire partition. So, to conduct these tests.
Test To Demonstrate Position-Dependent HDD Performance Degradation
I setup 4 partitions on this "1.5TB" drive in order to be able to test performance at different physical regions of the disk drive.

Each test transferred a total of 2GB of data, with a 2MB block size transfer
All values in MB/sec (e.e. Partition 'A' has SeqWrite=123MB/sec, SeqRead=124MB/sec, and RandomAccessRead=87MB/sec)

Disk formatted to 1400MB w/ 32KB cluster-size, NTFS
Partition A=0-525GB, B=526-1050GB, C=1051-1300GB, D=1300-1400GB

Drv SW SR RaR
A....123 124 087
B....110 110 080
C....090 090 069
D....072 072 054

As expected, performance decreased substantially as the tests were run physically closer to the maximum capacity of the drive
(the last partition D (100GB) spanning the 1300GB to 1400GB region of the drive)


edit:
updated to ~44 hours continuous testing completed on HDD so far
edit 20120213:
to separate the performance test results in a quote block to help them stand out, and to add this cross-ref to another of my posts on HDD setup v. performance http://www.hardwareanalysis.com/content/topic/77951/#593366

Yeah i'm going to get 2x spinpoint f3's. very good price n benches.
2tb drives of the same performance would cost about double!

...I just bought a 1.5TB drive from Newegg (in US) for
$60 (~$40/TB) by waiting for a promo offer.
Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148337


Just thought I'd update almost exactly one year later on this drive...just to let the above doomsayers breathe easier. (the $60 price is pre-Thailand floods, although it should be also noted that Seagate didn't suffer nearly as much production impact as the other drive makers)

The drive is still fine (SMART attribs), having spent the last year running 24hours a day, all power management is disabled (no spin-down/spin-up cycles). It's only been through about 10 power-on/off cycles (system updates). It gets quite a bit of R/W use. It's loaded with about 400GB of progs/apps/data.

Today's performance per HD Tune:
~125MB/s avg first 0-30% of drive
~108MB/s avg last 31-100% of drive
140MB/s burst
13ms Access Time

Note: higher performance in the first parts of the drive is normal for mechanical drives...performance derates as the heads track across the platters in these drives. This is the primary reason I limit the first partition to about the first 10% of these larger drives and put all OS/apps/data requiring the highest performance in that partition. And, where high performance is needed all-around, I may limit real-time usage to the top 30% of all the drives in a multi-drive system, using the latter 70% for archive/redundancy-type stuff.

edit to add:
By they way, the drives in my Windows systems are also constantly checked by Passmark's freeware Disk Checkup (I recommend...very decent drive health/failure "prediction" program) and the detailed HD Tune error scan is performed about once each month on each drive.
